Abstract

Ein Bildschirm mit einer Leuchtstoffzubereitung, die einen Leuchtstoff und eine Leuchtstoffbeschichtung mit einer Gruppe von Metall-Sauerstoff-Verbindungen umfaßt, wobei die Gruppe der Metall-Sauerstoff-Verbindungen eine Yttrium-Sauerstoffverbindung enthält, zeichnet sich durch eine überraschend verbesserte Bildschirmhelligkeit, Farbreinheit und Haftung der Leuchtstoffzubereitung auf dem Bildschirmglas aus Die Leuchtstoffschicht zeigt eine hohe Packungsdichte des Leuchtstoffmaterials. Die Leuchtstoffschicht weist eine gute Homogenität auf und ist frei von

A screen with a phosphor preparation which comprises a phosphor and a phosphor coating with a group of metal-oxygen compounds, the group of metal-oxygen compounds containing a yttrium-oxygen compound, is characterized by a surprisingly improved screen brightness, color purity and adhesion of the Phosphor preparation on the screen glass from The phosphor layer shows a high packing density of the phosphor material. The phosphor layer has good homogeneity and is free of
